Just received a great news from IOUG that three of my presentations were accepted for Collaborate 17.

. Session #724: Oracle DBAs, It is time to have a first taste of Oracle Database Cloud Service

Abstract: As an important part of Oracle Cloud offering, Oracle Database Cloud service provides an easy of use enterprise-proven highly available and scalable database service. Oracle database cloud service can be the first “going to Cloud” that you, an Oracle DBA may experience. This session helps you get the first taste of Oracle Database Cloud service. It will examine choices of of database cloud services and help you to determine which one would fit in your business requirement. It will also discuss the technical expects of each of cloud services. Through a few examples, the session will discuss the DBA tasks and how you would perform in the new database environment ranging from creating database cloud service to managing the databases.

Abstract :By introducing In-Memory column store, Oracle Database In-Memory (DBIM) significantly improves the performance for analytic queries as well as mixed workloads. Come to this session to learn Oracle Database In Memory under the hood: the dual format memory architecture and configuration, how the data is populated into In-Memory column store and it helps query performance. . This presentation also covers further enhancements of DBIM in Oracle Database 12cR2 : Join group, and In-memory expression, In Memory active Data Guard support etc. Through some case studies of business analytics projects, this presentation covers the practices of leveraging DBIM to improve the query performance of business analytic applications and how to use In Memory advisor to determine the objects that need to be loaded into In memory column storage . We also will present some analysis on the performance gains by using IM memory features and when and how these gains can be achieved.

Abstract: In this session we will share some of our experience on upgrading different versions of Oracle databases to the latest Oracle 12c. Attend this session you will learn the upgrade tools and various upgrade paths that help you plan your upcoming database upgrades. This will include upgrade methods for multitenant databases. Another focus area of this session is Oracle RAC database upgrade which includes Oracle Grid Infrastructure upgrade and Oracle RAC database upgrade. You will also learn how to use the rolling upgrade for Oracle Clusterware and ASM and Oracle RAC database to reduce the database downtime.

And it will be my great honor to join my fellow Oracle ACE Directors and Oracle ACEs as a co-speaker for their sessions:

And at last , but certainly not least, I am waiting for IOUG Collaborate 17 conference committee to accept one of important sessions in Cloud area: the IOUG Cloud SIG session: Session #711 Cloud Experience-To the Cloud and Back -Hands on Workshop by Steve Lemme, Charles Kim, Try Logon, Erik Benner, Kai Yu, Seth Miller.

If you are thinking about building Oracle Linux or Oracle VM based systems for your Oracle databases, for example building a private cloud type of system to consolidate your databases,. have you thought about the hardware infrastructure that your rest of platform will be built upon. One thing that you need to make sure is that the infrastructure stack is certified and validated for the software platform stack such as Oracle Linux/Oracle VM and the Oracle database.

The nice thing about this is that as a customer, you should not spend your resources for this complex and time consuming certification and validation process as various hardware vendors will partner with Oracle to establish the validated configurations. But you need to make sure that you select the proper infrastructure and OS based on the validated configurations. Since starting working on Oracle Linux and Oracle VM in 2009 , it has been my team’s responsibility to work with Oracle Linux and Oracle VM team to certify and validate Infrastructure such as Dell servers, storage and networking components with Oracle VM and Oracle Linux Unbreakable Kernel (UEK). And we posted the validated configurations on Oracle Linux and Oracle VM Validated Configuration (OVC) website : http://www.oracle.com/technetwork/topics/linux/validated-configurations-085828.html .

This website documented pre-tested , validated configurations and best practices of running Oracle Linux and Oracle VM on various infrastructure such as Dell PowerEdge servers, Dell Storage and Network. With each of the validated configuration, customers can run their production Oracle database either with Oracle Linux or Oracle VM as a database platform.

You can get a completed list of the configurations with this link: http://linux.oracle.com/pls/apex/f?p=102:1. On this link, you can type a Hardware vendor name and you can get a list of the validated configuration with various hardware. For example,. if you type Dell to search, it will come back with 55 configurations as today (10/19/2016). The list consists of the latest servers such as Dell PowerEdge R930 and various Dell Storages.

The Oracle OpenWorld 2013 will be held from Sunday September 22 to Thursday September 26. This is my 8th year Oracle OpenWorld experience. Since Oracle OpenWorld 2006, I have given total 16 Oracle OpenWorld presentations in the last 7 Oracle OpenWorld conferences. As usually this year my Oracle OpenWorld participation will start with two days Oracle ACE director Oracle product briefing in Oracle Cooperation Headquarter in Redwood shore on Thursday and Friday . After having a Saturday break, I will start my Oracle OpenWorld 2013 journey which includes six presentation/panel sessions and many meetings and networking activities. The most importantly I will have chances to meet many friends in Oracle community from different parts of the world. Here I list the six sessions that I will present or participate. It is my honor to have the opportunity to co-present these sessions with the great speakers from the Oracle community. And I look forward to having great discussions with those who are interested in the related topics:

Besides of my presentations, I also plan to attend some technical sessions including some OakTableWorld sessions and technical deep dive sessions. I will have some meetings with Oracle engineers and product managers in Oracle virtualization, Oracle RAC and Oracle Linux .

There is less than one week before Collaborate 13 conference. As a reference, I list the schedule of all of presentations and panels I will present or co-present here. Since Collaborate 13 conference allows us to download the presentations and whitepapers prior to the conference, the link with each of these titles leads to the page where you can download the presentation ppts and whitepaper.

The call for papers will last about one month and close at Friday, April 12, 11:59 p.m. PDT. For those of us who want to share their experences and technology inovation at this biggest information technology event in the world, we need to come up some topics and submit to the conference commitee by the April 12th deadline. Since 2006 Oracle OpenWorld when I gave my very first presentation at this event, I have been very fortune to speak at the conference 16 times. I look forward to having another year to continue my contributions to the conference.

I listed all of my previous Oracle OpenWorld presentation for reference. Here I want to thank the people who also contributed to these presentations including my co-speakers of some sessions, and the conference commitee who gave me the opportunity to present and the audiences who participated and supported me during the presentations.

My original backgroud was Oracle DBA and Oracle Applications DBA. My experiences was mainly on managing large Oracle RAC databases and Oracle E-Business applications suite running on complex muitple nodes environment such an Oracle Grid. In late 2008, as a part of addtional responsibilites of my job, I started working on Oracle virtualization technology specifically Oracle VM for X86-64 platform . Since then Oracle VM has become of one of my favour technologies. Natually I started looking at the best practices of running and deployment Oracle RAC databas, Oracle E-Business suite applications on the Oracle VM enviroment. The Oracle OpenWorld 2009 confernece allowed me to give three presentation sessions about my work on Oracle VM technology:

In 2010, Oracle Introduced the Oracle E-Business Oracle VM template. I was working on a project for which I needed to deploy Oracle E-Business Applications on Oracle VM environment . However I noticed that the Oracle EBS VM template downloaded from Oracle was a general template for the Oracle EBS vision instance. For the project, I needed to find out a way to virtualize the exisiting production Oracle E-Business suite system that currently ran on the physical environment . That is the backround that I came up the solution to migrate the Oracle EBS suite t to a virtual environment. As a result of the project, I put toegther a whitepaper about this solution:

I also worked on provisioning database and applications using Oracle Enterprise Manager’s Software library and provisioning procedures It can be considerred the early version of Oracle Cloud application provioning methods. Built in with Oracle Enterprise Grid control 10g, this method can quickly provision multiple node Oracle 10g RAC . Some of the early projects were presented at Oracle OpenWorld and Collaborate conferences:

As a part of Oracle Enetrprise Manager 12c cloud beta efforts, I worked with Oracle EM12c product engineers and product managers on a Dell | Oracle joint Oracle cloud project. This project aimed to architect and implement a privare cloud solution based on Oracle VM and managed by Oracle Enterprise Manager 12c. By importing Oracle VM templates into the Oracle Enterprise Manager 12c’s software library, on this project we were able to implement the self service provisioning of applications in the Oracle cloud environment using Oracle VM templates. The result of this project was presented at Oracle OpenWorld 2011, right after Oracle officially announced Oracle Enetrprise Manager 12c, total cloud control solution.

In 2012, as Oracle released new version of Oracle VM 3.0, we upgraded this cloud to Oracle VM 3.1.1 and implemented the self provisioning multiple tier applications using Oracle virtual assembilies. the newer version of Oracle cloud was presentated at Oracle Openworld 2012:
